COVER-REMOVIN G DEVICE.

Patented Mar. 14, 1922.

Application led June 21, 1920. Serial No. 390,373.

To all whom it may concer-n Be it known that I, UTAKICHI KAWASAKI, a citizen 'of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented new and useful Improvements in Cover-RemovingDevices, of which the followingv is a specification.

This invention relates to improvements in Cover or `lid lifting devices of the type carried on the cover of a can or other receptacle and which operates when .turned to lift the cover by pressing upon the receptacle.

The primary object of the invention isy to provide a device of the character described Ywhich will be exceptionally cheap, simple,

as to construction, reliable iny operation, and which will do away with the necessity of punching a hole in the cover and the employment of a pivot pin whereby the air-tight seal of the cover is not effected.. v

It is possible with the cover lifting means of the art to rotate them through 360 and very often much difficulty is experienced in putting the cover back in place when these devices are turned in the wrong direction and lie in theway of the cover. Also, these devices workv loose on their pivots after continued use and fail to operate properly.

My invention contemplates removal of the vforegoing objections by provision of a device which cannot be turned completely around,.and by-elimination ofpivot pins.

The invention possesses other advantages and features, some of which, with the foregoing will be set forth at length in the following description wherein I shall outline in full that form of the invention which I have selected for illustration in the drawings accompanying and forming a part of the pres# ent specification. In said drawings I have shown one form of the construction of my invention, but it isto be understood that I do not limit myself to such form, since the invention as expressed in the claims may be embodied in a plurality of forms'.

Figure 14 is aside elevation of the member of Figure 13.

Figure 15 is a. detail bottom plan of the part of the device on which the member of Figures 13 and 14 is mounted.

In the present embodiment of the invention, I employ a stationary member 16 on the lid 17 of a receptacle 18 and a movable or rocking member 19. associated with the member 16. The member 19 is adapted to engage the lid flangef() on the receptacle when turning so as to edect a prying or liftingl up action and to lift the lid from the receptacle.

In carrying out the inventiomthe lid 17 is provided with an extension 21 on one side thereof, of which extension the member 16 is formed, said lip being bent upward-ly Aso as to parallel and lie spaced from theV side of the lid, and being provided with an angular central opening 2Q. A tongue 23 extends from the lid at right angles thereto before the devicel is assembled. The opening is enlarged or under-cut, as at 24, at opporsitesides so as to provide flanges 25 on oppositesides of the opening.

They member 19 is formed from a Hat metal blank shown iny Figure 4 and is bent right angularly as shown in Figures 13 and 14 so as to provide an operating or hand of a part of the the member 14 is moved upwardly until the Y portion 26 thereof reaches the upper side ofthe opening 22. The member 19 is pre-V vented from movement laterally lby engagement of the flanges 25 in the ends ofthe notches 31. The tongue 23 isthen bent up- Y wardly until it extends over and engages the tongue 30 and these tongues hold the parts in place. By turning the member 19 in either direction, it is rocked and' one ofV`V` A the legs iis moved downwardly'behindone of the flanges 25 and presses upon the flange 20 on the receptacle. This forces the lid upand off of the receptacle. As thelegs move down they extend through. the en.-`

largements 24 of said opening 22 inthel member 16 and at all times are behind the flanges 25 so as to prevent outward withdrawal of the member 19. ,Y

It will thus be seen that with my device the lid may be quickly lifted by a slight turn of the member 19 and that said member is prevented from being turned through 360o it being permitted but .approximately ofan arc in eitherV direction. This'insures the member 19 being in the rightposition when the lid is to be replaced. When this is done, the lid in engaging the projected leg of the member `19 will move said leg and member to normal position and this does not interfere with the replacing of the` `yiid. 1 f

My' device eliminates the forming of holes in the receptacle or cover proper and can be cheaply stampedV out of sheet metal. quicklyassembled, and when assembled, will not loosen but operate reliably'at all times. v

Referring particularly to Figures 5, 6, 7 and 8 the modified form shownltherein Y comp-rises stationary members 33 formed spaced from the side of the cover.

on the cover 34 of a. receptacle 35. This member 33 is tapered to a rounded point towards its free end and is notched as at 36', on opposed sides thereof when joined' to the Craven-being bent up parallel to and i Vits free end. said member is providedV withy an opening 37 formed by striking the metal inwardly.. This provides a series of bandable tongues 38 around the edges ofthe opening. lThe member 39 is bent right angularly from a. metal blanlrand one portion thereof is notched or out away at spaced Near points as at 40 to provide legs 41 and a tongue v42between and .spaced from said legs. l The tongue is formed with an openingv43. v.

VIn assembling this formof the invention,

the member 39 is placed with its legs 41 behind the member' 33 and so that the-handle portion 44v thereof extends outwardly over the upper edge of said member 33. The legs 41 extendthrough the Anotches 36 and are rounded on. their lower ends. so asto engage and 'effect' a prying up action on theflange 45' of said receptacle.` The pivot for the memberl 3 9- is provided by extending the tongues 38 through the-opening 43 andi bending said tongues outwardly. This secures the member 39 in place nand provides an effective pivot. This form oftheinvention can also beV moved in eitherdirection to effect 'a lifting of the coverpandcannot rotate through 160o being limited as to this by engagementof the portion with the'V member 33.

AReferring to Figures 9', 10,7211, and 12, the Vother modified form comprises a staton ary member 47 bent up from and formed inl tegral with the cover 48 inthe same manner as the corresponding memberfofv the other forms of the invention. l

This member' is provided'with an angular opening 49 therein and with two small slots 50 adjacent to the point where said member is joined to the cover. The 'right angular member 51 has two legs 52 having inward.. notches 53 therein at their inner ends. TheV` opening 49 is formed with two slots 54 onv normalV position and `the memberV 51 :isz

locked in place. By turning said memberl 51-7 one ofthe legs is extendedthroughone of the slots 50 andi willV engagethelcover flange 55 on the receptacle so as to liftlthe lid. This form'isvery-'simple and capable offbeing easilymade and inserted'.
